unmarried stay @home mum separation advice please

[fridaysforfuturemum]

My partner asked for a separation in January.
We are joint owners of our home and have been living in a toxic atmosphere since then. We have two teenagers at High school. We're not married and I know I have no legal rights on anything but half the house. It was a joint agreement that I leave my job to be a stay@home mum. My partner now says it was my decision and legally he does not have to give me equal share of the savings etc..
I have no money as we just had a joint account. I really want to stay in my home with my kids. (they will stay with me one week, then him the next...)
The solicitors I spoke to were not interested in helping me because they said I was a cohabitee and had no rights. Appeal to his better nature was their top tip!
Can anyone suggest what kind of professional would be able to help me put a financial settlement proposal together that is fair and equal,takes into account what I have contributed to our family over the last 16 years and splits everything 50/50?
I'm saying to him it's about doing the right thing and what's morally right rather than what I'm legally entitled to. I asked him to treat me as if we have been married. We have been together 26 years :(
I've been a trusting fool like so many other women before me...

Agree with get married if you want the rights of marriage.

I often see the statement that more education is needed, but also the statement that men know exactly what they are doing. How is it that male members of society learn these things, but females don't?

I'd suggest it's like many things in life, some people, irrespective of sex simply don't make the effort to engage with the easily accessible and widely published information already available. If people choose to be ignorant, they should expect to make more mistakes and live with the stronger consequences.

Honstly OP do not waste money on solicitors. Iam one myself, though not in family law
The fact is that if he is offering you more than what you are legally entitled to, take it. What you would be entitled to if you were married is irrelevant.
